Abstract

An (electric) arc quenching device for an electrical switch, especially for an automatic cut-out (circuit-breaker) and contactor consists of one movable and one fixed contact piece (11, 12) which are arranged in a quenching chamber space (22). During a switching operation, an arc is produced at the contact location, the base points of which arc commutate from the contact pieces (11, 12) to arc conduction rails (13, 14, 16; 18) which feed the arc to a quenching device (15). In order to accelerate the movement of the arc, a locking plate (21) is provided in front of the contact location (11, 12), seen in the arc running direction (P), which locking plate frontally seals the quenching chamber space (22) in the region in front of the contact location (11, 12), so that gas flow in this region in front of the contact location (11, 12) is prevented. <IMAGE>
